00:02 Good day, everyone.

00:15 My name is Adekunle.

00:16 I'll be teaching you chemistry,

00:18 and the topic we have now is chemical industry.

00:21 Our objective for today

00:27 are understand what chemical industry is,

00:31 know the raw materials used in different chemical industry,

00:34 understand the classes of chemical industry

00:37 and the importance of chemical industry

00:40 to an individual and to the nation at large.

00:44 What is chemical industry?

00:47 A chemical industry is an industry that uses

00:49 the knowledge of chemistry,

00:51 to make chemicals from chemicals

00:54 called raw materials.

00:58 What are raw materials?

01:00 These are the starting materials used

01:03 for the production of all the useful materials.

01:07 The basic raw materials we use in chemical industries

01:10 are air,

01:12 saw for, petroleum,

01:15 coal,

01:16 and so on and so forth.

01:19 What are the importance of raw materials?

01:22 Without raw materials,

01:24 there can't be finished products.

01:26 Therefore, in classifying chemical industry,

01:29 there is need for laws to take note of our raw materials.

01:34 For example, sort is obtained from sea water.

01:39 I believe you are just getting that now.

01:41 Welcome to chemical industry and food.

01:45 What are the classes of chemical industry?

01:50 Basically, chemical industries can be grouped into two,

01:53 heavy chemicals and fine chemicals.

01:57 What are heavy chemicals?

01:59 These are chemicals that are used in large quantities.

02:04 They are very necessary so they are produced in large quantities.

02:08 And because they are produced in large quantities,

02:10 it makes them, it makes us call them heavy.

02:14 And then they are also used in processing

02:17 other chemicals too.

02:19 What are the examples of heavy chemicals?

02:21 We have, Tetrausophys 6 acid,

02:24 a very important chemical.

02:26 Sodium, I do that also called caustic soda

02:30 in still some industry as we speak.

02:32 Very, very important.

02:34 We have translated five acid, HNO3.

02:37 Very important, is it ammonia?

02:40 NH3, very, very important.

02:42 Hydrochloric acid,

02:43 important in the industry,

02:45 and bleaching powder.

02:46 Very, very, very important chemicals.

02:51 And these chemicals are actually used for producing

02:54 fertilizer, soaps, glass.

02:56 Those things that you use almost on a daily basis.

03:00 The second class of chemical industry

03:04 are the fine chemicals that are produced in Iperity

03:09 because of their usage.

03:11 And then they are also produced in small quantities

03:14 because they are only needed for specific industrial

03:17 and domestic purposes.

03:19 Examples are dye stoves, additifs,

03:22 and additive chemicals, drugs.

03:24 You have formulary drugs.

03:25 They are not just produced anyhow.

03:27 Perfumes, you don't use producing anyhow.

03:29 You are produced to the taste of what?

03:32 Peerity.

03:33 The nest.

03:39 Types of chemical industries.

03:43 And chemical industry can be categorized

03:44 into various types based on your raw materials used.

03:48 And the product formed.

03:50 Like I've told you before, raw materials are what we use

03:53 to produce useful products.

03:56 And the product in concern also is very important

03:59 because a particular raw materials can be used

04:02 to make different products.

04:04 The first we are going to look at is air.

04:07 As you likely know, that air is a mixture of gases.

04:11 Over the major components are oxygen and nitrogen.

04:15 Oxygen containing 21% while nitrogen containing about 78%.

04:21 They are very important in industries.

04:24 The first one I will talk about is air.

04:26 And that part of air, the component of air

04:30 I'm going to speak about is oxygen.

04:33 Oxygen and the product from oxygen

04:36 is all the ascertaining flame.

04:38 Use for coating, use in steel industry for coating metals.

04:43 And the industry that makes them,

04:45 that makes it of them, are the steel and wedding industry.

04:49 Like I said, the second one about the component of air

04:53 that we are going to talk about is nitrogen.

04:56 Nitrogen, even with the use of nitrogen,

04:58 you have an intermediate product.

05:00 That is not written here, which is ammonia.

05:02 Very important chemicals in the industry.

05:05 And the other basic products are fertilizers,

05:07 explosives, plastics, watching soda,

05:11 and ammonium chloride.

05:12 These are products from ammonia, for the use of water,

05:16 nitrogen, and the intermediate product is ammonia.

05:21 What are the chemical industries that makes these of these?

05:23 We have the fertilizer industry, the water works

05:27 and plastic industry.

05:29 If your raw material is petroleum-feet socks,

05:33 petroleum has different fractions, even from crude oil.

05:37 It has different fractions.

05:38 And because of that, they are the rate of crude oil

05:41 that you can get from petroleum.

05:43 Since '35, for example, pharmaceuticals,

05:48 or various kinds of drugs, can also be gotten

05:51 just from your petroleum-feet socks.

05:53 We have annealing, we have dyes, we have plastics,

05:57 rubber, paint, detergent, and even many more

06:01 that we can't mention simply from petroleum.

06:05 And the chemical industry that makes it of them

06:07 are the paint industry, the rubber industries,

06:10 the plastics industry, fertilizers, detergent,

06:14 pharmaceutical industries.

06:15 If our raw material is coal, our basic products

06:22 will be plastics, explosives, dyes, coagas, ammonia,

06:27 and so on.

06:28 And the chemical industries that produce all these

06:31 are the plastic industries, the dyes,

06:33 and explosives industries.

06:37 If our raw material is calcium-throwed carbonate-4,

06:42 which generally called limestone, as we can find,

06:46 in e-way crude Portland cement,

06:48 and all the maybe also dungote cement.

06:52 You can come up if you happen to visit any of these places,

06:55 you will see the use of calcium-throwed carbonate-4.

07:00 And the basic products we have familiar with them,

07:03 the blishing powder that I told you before,

07:05 the washing soda and mortar, mortar from cement,

07:09 and this chemical industry, at the water walls,

07:12 the building cement and glass industries.

07:15 Some want to become an engineer,

07:18 some want to make it over-building,

07:21 I mean, some want to be building,

07:23 and some want to be into civil engineering,

07:27 you will actually need the knowledge of these industries.

07:31 And then, if our raw material is that one that is gotten

07:36 from sea water, salt, sodium chloride that you use at home,

07:40 our basic products will be plastics, insecticide,

07:44 textiles, paper, soap, and fabrics.

07:47 It might interest you that all these cannot be produced

07:50 without an IOTA of salt, sodium chloride.

07:54 And the chemical industry that makes of them,

07:56 and the plastics, the textiles,

07:58 the insecticides industries, soap industry,

08:01 and fabrics industries.

08:05 If our raw material is so-for,

08:09 our basic products will be fertilizers.

08:14 Fatalizers are so-for inside.

08:16 Paint, so-for is one of the pigments in paint.

08:19 Explosives, mixes of so-for, so-for from H2SO4.

08:23 Dice, synthetic fibers, and accumulators.

08:27 Accumulators that also resists acid

08:29 is a major accumulators even used in your cars.

08:34 Chemical industries that makes of this raw material,

08:38 so-for, are the fertilizers, paints,

08:42 explosives, synthetic fibers, and accumulator industries.

08:46 If our raw material is metallic oils, metallic oils from iron,

08:52 various products can be getting from iron.

08:54 These products can be gotten from aluminum and even copper.

08:58 And we see coat flammaries.

09:02 You use collayer at home.

09:04 All these are made from iron.

09:06 Some are made from aluminum.

09:08 Dylene and cotton machines.

09:10 Also made from iron and aluminum.

09:14 Vacals, tractors, roofing sheets,

09:17 all of these medias of iron aluminum at one point,

09:20 or the other, and copper too.

09:21 Copper, majorly for cables, some aluminum too.

09:25 Also, the densies focus mainly on the use of iron and aluminum.

09:29 They always, all of these of any of these three,

09:32 iron aluminum, copper, pipes, wires, copper,

09:36 and aluminum, majorly.

09:37 And so on that we can't even mention here.

09:40 The nests are the industries that makes of them.

09:43 They also provide industry, and metallurgic industry.

09:47 Metallurgic industries actually involve melting metals

09:49 to make different products become metal and aluminum

09:53 and copper to make different kinds of products.

09:58 What are the importance of this chemical industry?

10:01 To an individual and to the nation at large.

10:04 To an individual, in India, for example,

10:07 highly skilled workers, such as chemists, engineers,

10:10 and technicians, are by themselves able to get,

10:15 do a job by themselves, or be employed by good chemical industries.

10:21 So by a version of that, there's an employment opportunities

10:25 for that individual, either for himself,

10:27 or to even create for all of us, to the nation.

10:32 A chemical industry is produced, and it's from foreign trade.

10:35 All these products we have talked about, they can be less changed,

10:38 they can be transferred to other countries,

10:40 and used to make money for the nation.

10:42 And then because of all these products that we are producing

10:46 from chemical industries, the standard of living

10:48 of the Nigerians are being proved

10:51 because they are able to make use of the products

10:55 from all these raw materials from chemical industry.

10:59 And to the nation, chemical industries provide

11:04 earnings from foreign trade.

11:06 Foreign exchange, we are able to transfer some of these products

11:10 to other countries to make estimates, to make exchange,

11:13 and to make money.

11:15 Also, by virtue of the products produced

11:18 from chemical industries, the standard of living

11:21 of the engineers are being proved.

11:23 They are able to make use of the products

11:25 from chemical industries.

11:27 And lastly, it provides employment opportunities

11:30 for the citizens.

11:32 Many are working in chemical industries, very, very many,

11:36 are working in chemical industries as we speak.

11:38 And then there, it creates what an employment opportunities

11:43 for the nation.

11:44 After listening to everything we have talked about

11:49 in chemical industry, there is need for you to be evaluated.

11:54 And the first question I would like to ask you

11:56 is differentiate between the two types of chemicals.

12:00 I believe you can answer that by now.

12:02 And I mentioned any three raw materials

12:05 and state five products, obtainable from each of them.

12:10 State, the next question is state four advantages

12:14 of chemical industry.

12:16 And the last I would like to ask you

12:17 is give four examples each of fine chemicals

12:22 and heavy chemicals.

12:24 Thank you for watching.

12:29 I am adequately.

12:31 See you next time.

12:32 (upbeat music)
